Structure of bright 2MASS galaxies: 2D fits to the K-S-band surface brightness profiles
2MASS K-S-band surface brightness profiles
2014/12/24
The unprecedented sky coverage and photometric uniformity of the Two Micron All Sky Survey (2MASS) provides a rich resource for obtaining a detailed understanding of the galaxies populating our local ...
On the origin of cold dark matter halo density profiles
dark matter large-scale structure of the universe
2014/12/24
N-body simulations predict that cold dark matter (CDM) halo-assembly occurs in two phases: (i) a fast-accretion phase with a rapidly deepening potential well; and (ii) a slow-accretion phase character...
The Na D profiles of nearby low-power radio sources: Jets powering outflows
galaxies: active — galaxies:radio continuum — galaxies:ISM
2011/9/28
We have analyzed the properties of the Na D doublet lines in a large sample of 691 radio galaxies using the Sloan Digital Sky Survey (SDSS). These radio galaxies are resolved in the FIRST survey, have...
The AMIGA sample of isolated galaxies: VIII. The rate of asymmetric HI profiles in spiral galaxies

2011/9/27
(abridged) Measures of the HI properties of a galaxy are among the most sensitive interaction diagnostic at our disposal. We report here on a study of HI profile asymmetries (e.g., lopsidedness) in a ...

DARK MATTER HALOES：AN ADDITIONAL CRITERION FOR THE CHOICE OF FITTING DENSITY PROFILES
cosmology dark matter
2009/3/5
Simulated dark matter haloes are tted by self-similar, universal
density pro les, where the scaled parameters depend only on a scaled (truncation)
radius, = R=r0, which, in turn, is supposed to b...

ON THE DENSITY AND SURFACE BRIGHTNESS PROFILES IN GLOBULAR STAR CLUSTERS
globular clusters general
2009/2/13
A model of mass distribution, applicable to globular star clusters
and proposed earlier, is reconsidered. It is shown that it can be related to the
well-known Plummer-Schuster formula, and the equat...
